Find the first partial derivative with respect to w
Find the first partial derivative with respect to v
∂w∂a=v1
Simplify
a=vw
Find the first partial derivative by treating the variable v as a constant and differentiating with respect to w
∂w∂a=∂w∂(vw)
Use differentiation rule ∂x∂(g(x)f(x))=(g(x))2∂x∂(f(x))×g(x)−f(x)×∂x∂(g(x))
∂w∂a=v2∂w∂(w)v−w×∂w∂(v)
Use ∂x∂xn=nxn−1 to find derivative
∂w∂a=v21×v−w×∂w∂(v)
Use ∂x∂(c)=0 to find derivative
∂w∂a=v21×v−w×0
Any expression multiplied by 1 remains the same
∂w∂a=v2v−w×0
Any expression multiplied by 0 equals 0
∂w∂a=v2v−0
Removing 0 doesn't change the value,so remove it from the expression
∂w∂a=v2v
